Road maintenance activities often contribute to traffic congestion. The process of repairing roads, which can be time-consuming, inevitably leads to significant disruptions in traffic flow and inconveniencing both road users and residents living near the construction area. Fast-drying concrete is an innovative approach that drastically reduces the duration of lane closures during repairs. Such advancements offer numerous advantages. This research was conducted to evaluate the traffic implications associated with the utilization of fast-drying concrete and to simulate the length of the work zone during road pavement repairs along a provincial road segment in Karangawen, an agglomeration area in Central Java, Indonesia. Under normal conditions in this area, daily peak patterns (as traffic patterns in urban areas) are seen on weekdays and Saturdays, while on Sundays, traffic variations tend to be low. The highest hourly traffic volume reached 4634 pcu/h, occurring on Saturday. Speed ranges from 50 to 90 km/h. Modeling is carried out with the assumption that traffic control (road closures system) is approached by a 2-legs-2-phases signalized intersection, with the distance between the legs is depending on the length of work-zone. In general, 45 m is the maximum length before traffic performance collapses.
